40 mm Woven Lashing: How to Specify the Webbing and Buckle

When comparing quotes for 40 mm woven lashing, check the webbing grade, buckle model and metres per pack. Tensipack’s 40 mm polyester one-way lashing has a linear breaking strength of 5,000 daN. Its system breaking strength of 8,500 daN applies to the webbing paired with the matching buckle in the tested configuration.

40 mm is a commonly used width for one-way woven lashing. This grade is typically supplied as a 100 m flat coil or 200 m loose-packed in a plastic bag. White and orange are available, and other colours can be made to order.

What Do 5,000 daN and 8,500 daN Mean?

5,000 daN Linear Breaking Strength

Linear breaking strength describes the force at which the webbing breaks when tested on its own. If two quotes both say “40 mm polyester lashing,” check the webbing model and the stated linear breaking strength on each. If you are setting a purchase specification, ask whether the quoted figure is a specified minimum, a typical value or the result from a particular sample.

8,500 daN System Breaking Strength

System breaking strength describes the performance of the webbing and buckle assembled for a specific test. The test configuration differs from a straight pull on a single length of webbing, so record the two figures separately when comparing offers. Ask for the webbing model, buckle model, threading instructions and test report reference behind the system figure. Cordstrap follows this approach in its published specifications by linking each system breaking strength to the recommended buckle. Cordstrap lashing specifications

For a cargo securing calculation, use the applicable rated force for the assembly and assess it against the securing arrangement, including the anchorage points, lashing angles and transport conditions. UNECE CTU Code

How to Match a Buckle to 40 mm Woven Lashing

When Buying Webbing and Buckles Together

Ask the supplier to list both model numbers on the quote and identify the combination covered by the system test. If the supplier offers both a forged and a welded buckle, ask which model was used for the quoted result and request the result for any proposed substitute. Both buckles may accept 40 mm webbing, while the test report may cover only one of them.

For repeat orders, put the approved webbing and buckle model numbers on the purchase order. If either component changes, your team can check the proposed replacement against the approved combination before shipment.

When Using Buckles You Already Have in Stock

Send the supplier the existing buckle’s manufacturer and model number. If the buckle is unmarked, send clear photos of both sides, the slot dimensions and any packaging label. These details help the supplier identify the hardware and check whether there is a test record for that pairing. If the pairing has yet to be verified, leave the system strength open on your quote comparison sheet.

100 m Flat Coil or 200 m Loose-Packed Bag?

Packing format Typical length What to confirm before ordering
Flat coil 100 m per coil Check the coil dimensions if you use a dispenser or have limited storage space at the packing station.
Loose-packed in a plastic bag 200 m per bag Confirm whether the 200 m is supplied as one continuous length if your cutting process requires it. Ask for packed dimensions and gross weight if you are comparing freight costs.

For an initial price comparison, divide the price per coil or bag by the metres supplied. If your team cuts fixed lengths, also compare the cost per usable cut length.

For example, if an approved securing layout calls for 6 m lengths, a continuous 100 m coil yields 16 full lengths, with 4 m left over. A continuous 200 m bag yields 33 full lengths, with 2 m left over. Divide the quoted pack price by 16 or 33 to see what each usable length costs if the offcuts have no other use. Then add the cost of the buckles required for the job.

White and orange are available. For a custom colour, send a physical swatch or colour reference and confirm the sample approval process, minimum order and lead time before placing the order.

What to Include in a 40 mm Woven Lashing RFQ

If you are sourcing 40 mm woven lashing and matching buckles, send Tensipack your preferred packing format, colour and order quantity. If you plan to use buckles you already stock, include the model number or photos so we can review the pairing before quoting. Contact Tensipack.
